The outer extremities 19 of the carlines, when positioned on the side plates, are secured within the outer edge 21 of the inclined flanges of the side plates, so that the carlines do not extend beyond the outside edges 2l of the side plates.

The intermediate roof sheet sections are also arched to conform to the pitch of the roof, and are comprised of a main body extending clear across the car and terminating in vertical depending flanges 23 at the outside edges of the side plates. At each side edge, these intermediate roof sheet sections are offset upwardly a height sucient to fit Vover the transverse flanges of the car-- line, so that the main body 22 of the sheet may make Contact `with the top face of the side plates at the eaves as at 24, which contact together with the depending flanges 23 of such main body prevent entrance of water into the car.

These offset portions 25 extend clear across the car and are preferably of greater width than the width of the flanges 16 so as to clear the widened portions 18 of such flanges at the top face of the side-plates and also to enable the roof sheet sections to be drawn tightly to the earlines so that they may be properly secured together, notwithstanding slight irregularities in the spacing of said carlines on said side plates, and such widen ing of said offset portions also helps to prevent buckling of the roof sheet sections.

These offset portions of the roof sheets terminate in carline engaging and enclosing flanges, and, in the present instance, one side Hanging consists of an upwardlyy projecting portion'26 Whose extremity is curved or rounded as at 27 to conform to and to engage the greater portion of the top web of the carline.

The offset portion of the opposite side edge of such roof section terminates somewhat similarly, except that it is formed to enclose the side'flanging of its next adjacent sheet, and is provided with an upwardly projecting portion 28 which is bent at 29 to conform with the top web of the carline and thence extends down as at 31 over the opposite side web of the carline, so that it encloses substantially the entire upwardly projecting portion of the adjacent carline.

Each of the side websrof the carlines are perforated as shown at 32 to receive the Shanks of rivets that, in the present instance, are used to secure the roof sheets tightly to the carlines. The end roof sheet sections are formed similarly to the intermediate roofv sheet sect-ion, except that the. edge that ex tends over the end plate of the car is not offset nor are flanges provided to engage a carline but instead the edge terminates in a projecting portion of the adjacent carlineV and also the flanging of the next adjacent sheet sot-hat the side Q8 of such Hanging makes contact with the adjacent side web of the adjacent carline and the top portion 29 and depending portion 31 makes Contact with and encloses the side 26 and top 27 of said next adjacent roof sheetsection flanging.

The roof sheet sections are secured rieidlv `CJ u to the car by rows of rivets 35 that pass through the side Q8 of the Hanging of one side of the roof sheet and the side web of the cai-line adjacent to said side 2S. Another row of rivets 36 pass through the opposite side web of the carline and throughthe overelapping edges 26 and 81 of adjacent roof sheets. These rivets 35 and 3G are arranged so that each rivet forms the apex of a triangle in a horizontalplane and so that each rivet is substantially midway between two rivets on the opposite side web of the carline, thereby lessening the number of rivets required without reducing the strength of the roof as a whole. At the eaves ends, the roof sheets and carlines are riveted to the side plate by rivets 37 that pass through apertures 38 in thel offset portions of theroof sheets and apertures 39 in the widened portions 1S of t-he carlines and through the top flange of the side plates.

The Hanging of adjacent roof sheets at the eaves ends of the carlines are flattened and are lapped over the side plates as shown at 41 so that they are substantially in line with the depending eaves flanges 23 of the main body of the roof sheet sections, and as seen in Figs. 7 and 8.

A running board saddle and splice plate 42 is provided, having a horizont-al portion 43 which supports the usual ruiming boards 44 that are bolted to the portion 43 b v bolts 45, and the saddle is also provided with a depending portion 46 which is secured to the overdapped edges of the adjacent roof sheets at the ridge and to the adjacent side web of the carline, as shown in Fig. 2.

From the foregoing it will be noted a substantial rigid all-steel roof construction is provided which is comparatively simple to assemble by reason of the rouneed formation of the carlines and over-lapping roof sheet flanging which assembly is assisted by the offset 'portions enabling adjustment by reason of slight irregularities in spacing of the .carlines vand it Wil-1 alsobe observed that the The invention as hereinabove set forth is embodied in a particular forni of construe tion but .may be. variously embodiedV ufithin thescope of the claiins hereinafter inade.
